Overview

Our take on the Blaupunkt THA475PnP

Blaupunkt's  THA475PnP 4-channel amp pushes out 75 watts RMS per channel to four speakers, or can be bridged to drive 180 watts RMS to a pair of subwoofers or speakers. A direct auxiliary input lets you plug in your MP3 player or navigation device, a big plus if your factory receiver has no aux input. An automatic input detection circuit eliminates the need for a remote turn-on lead.

Little amp, big power

Blaupunkt's THA475PnP 4-channel amp pushes out 75 watts RMS per channel to four speakers, or can be bridged to drive 180 watts RMS to a pair of subwoofers or speakers. A direct auxiliary input lets you plug in your MP3 player or navigation device, a big plus if your factory receiver has no aux input. An automatic input detection circuit eliminates the need for a remote turn-on lead.

The THA475PnP produces big power from an ultra-compact housing, so it'll fit into some tight places in your vehicle. This full-range Class D amps uses miniaturized power transformers for cool, efficient operation so your speakers will sound fuller, with clearer highs, richer mids and more powerful bass.

I'm really happy with this unit so far. It was quick and easy to install and it filled my needs completely. I just needed an am to balance out my Punch 300 powered sub and this amp does just what I want it to do.

Features

Terminal Layout: For wiring convenience all the inputs, outputs, and controls are on one side of the amp.

Wire Terminals: The speaker output and power input terminals use removable plugs to attach the wires to the amp. Bare speaker wire, up to 10 gauge for power, ground, and remote and up to 12 gauge for the speakers, is held in place by a set screw, the plug then snaps onto the terminals on the amp.

Direct Aux Inputs: Two auxiliary sources (portable, DVD player, navigation system, etc) can be plugged directly into the 3.5mm mini-jacks on the amp (one each for the front and rear channels). If the same auxiliary source is to be use for all 4 channels, a Y-adapter should be used. Both the auxiliary and main inputs are amplified simultaneously, so the volume of each must be independently adjustable.

Bridgeable: The front and/or the back sections of the amp can be bridged independently, making it a 4, 3, or 2 channel amp.
